NoFlo Project Linting tool

noflo-lint can be utilizer for finding and analyzing all dependencies of a NoFlo project. It uses a graph as the entry point and traverses its nodes and sub-graphs to find and check all components used.

Basic usage

You can run noflo-lint with the command line using the following:

$ noflo-lint <baseDir> <graphName>

Configuration

The handling of the various NoFlo linting checks can be configured on three levels: ignore, warn, and error. Failing an error-level check will make the process exit with a non-zero exit code.

Currently the following checks are available:

• description: Whether the component has a textual description
• icon: Whether the component has an icon set
• port_descriptions: Whether all ports have textual descriptions
• wirepattern: Whether the component uses the WirePattern helper
• process_api: Whether the component uses the Process API
• asynccomponent: Whether the component uses the deprecated AsyncComponent API
• legacy_api: Whether the component uses legacy NoFlo API (i.e. not WirePattern or Process API)

Contributing

Additional checks can be added to the src/check.coffee file. Each "checker" receives a component instance to inspect. Another interesting area would be to inspect the connections in the graph. For example, detecting if there are unconnected required ports.
